传统的地热系统用于供暖和制冷。地 温度在50%到60%之间。它们是闭环或泵和卸载 安排。这篇文章讨论了如何使用来自澳大利亚的饮用水 作为热源和冷却源的水管。该系统使用热交换器 热泵和空气输送系统。热交换器使用3度的温度 达到冷却或加热的温度。热交换器的位置可以是 要么在主楼里，要么在大楼里。该系统的主体是一块扁平的铜线 大约132英寸长的卷轴可以由不锈钢控制 供水设施。建筑物中的热交换器在加热后返回饮用水 换到水管里。饮用水可以得到保护，以防止 来自热交换器的污染。

The conventional geothermal system is used for heating and cooling. Ground temperatures are between 50 and 60%. These are closed loop or pump and dump arrangements. This paper discusses using potable water from water mains as a source of heat and cooling. This system uses the heat exchanger, the heat pump, and the air delivery system. Heat exchangers use 3 degrees of temperature to achieve cooling or heating. The location of the heat exchanger can be either on the main or in the building. The system on the main, a wrapped flat copper coil around a stainless steel spool about 132 inches long, can be controlled by the water utility. The heat exchanger in the building returns potable water after a heat exchange into the water mains. The potable water can be protected to prevent contamination from a heat exchanger.
